Celebrating 10 Years of Piper Maddox

A decade of purpose, growth and impact in clean energy talent This year marks ten years of Piper Maddox, one of LHi Group’s fastest growing specialist brands, built with a clear purpose, to support the global clean energy transition and help protect the future of our planet through exceptional talent solutions.Founded in 2015 by Alex Cohen under the LHi Group, Piper Maddox was created with a belief that recruitment could be more than a commercial service, it could be a platform for positive change. From the outset, the brand committed fully to renewable energy and cleantech, stepping away from fossil fuels entirely and aligning its growth with the industries actively decarbonising the world. Over the past decade, Piper Maddox has become a trusted partner to some of the world’s most innovative clean energy organisations across the US and Europe, helping them build the teams shaping how energy is generated, stored and consumed.

At its core, Piper Maddox is driven by the belief that recruitment can be a force for good, contributing to a cleaner, more sustainable future, one hire, one partnership and one business at a time. From Vision to Global Brand As the energy sector began shifting towards renewables, it became clear that traditional recruitment models were struggling to keep pace with the urgency of change. The clean energy transition demanded specialist knowledge, speed and long-term thinking, not legacy approaches. Recognising this opportunity, Alex Cohen and LHi Group Founder, Tom Glanfield aligned on a shared ambition to build a recruitment brand dedicated entirely to clean energy and sustainability. Combining entrepreneurial platform, leadership and a strong cultural foundation, Piper Maddox was born as a values-led business designed to create long-term impact. From those early beginnings, the brand has expanded rapidly across Europe and North America, building leadership teams united by a shared purpose to accelerate the energy transition and support companies working to decarbonise the planet. “The success of Piper Maddox reflects what’s possible when purpose, people and platform align.
